JAMES M. DODGE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE LINK BELT ENGINEERING COMPANY, OF SAME PLACE.

ENDLESS BELT CONVEYER.

SPECIFICATION forming part of Letters Patent No. 672,358, dated April 16, 1901.

Application filed December 23, 1899. Serial No. 741,482. (No model.)

To all whom it may concern.-

Be it known that I, JAMES M. DODGE, a citizen of the United States, residingin Philadelphia, Pennsylvania, have invented certain Improvements in Endless-Belt Gonveyers, of which the following is a specification.

The object of my invention is to so construct an endless-belt conveyer that the material will be carried upward on the belt by the combined action of centrifugal force and adhesion. This object I attain in the following manner, reference being had to the accompanying drawings, in which- Figure 1 is a sectional view in which the sprocket guide-wheels and drive-wheels are shown in diagram, illustrating my invention. Fig. 2 is a detailed view of the upper portion of the elevator, showing the belt and drivechains at each side. Fig. 3 is a section on the line 3 3, Fig. 2. Fig. 4 is a view of a modification of my invention, wherein the idlers are shown in diagram similarly to Fig. 1. Fig. 5 is a section on the line 5 5, Fig. 2.

My invention is especially adapted for elevating ashes and like material, which will cause ordinary elevating mechanism, such as the buckets, to wear away rapidly. By my invention the ashes are simply placed upon the belt and are carried thereby bodily to the point of discharge.

A is an endless carrying-belt of any suitable form or made of any material.

I is the horizontal portion of the elevatingconveyer, at which point the belt is loaded with material. This horizontal portion can be of any length desired, according to the location of the apparatus.

I is the curved elevating portion, and I is the terminal or discharge end, of the elevator, situated above a floor E or receptacle E, into which the material is discharged.

The belt passes around a drum G at the base and past guide-wheels b b and around a wheel I) on a driven shaft B and returns over guide-wheels c and c.

As shown in Figs. 2 and '3, I preferably mount on each side of the belt A drive-chains a a, and the wheels I), b, and b are sprocketwheels adapted to the chains. A rapid motion in the direction of the arrows, Fig. 1, is imparted to the belt, and the driven shaft B is so situated that the belt is given an abrupt turn, so that the material will be thrown from the belt onto the floor or into a receptacle.

The several shafts carrying the sprocketwheels are adapted to bearings in the frame D, and E is a receiver or bin mounted on a floor or other structure E. The material, such as ashes, is dumped upon the belt at w and is rapidly carried forward and upward by the belt. The material owing to this motion adheres tenaciously to the belt until it reaches a point y, where the belt is abruptly turned, causing the ashes or other material to drop away from the belt and into the bin E, directly below this point.

I have found by a series of experiments that a steady stream of ashes or other mate rial can be carried from one floor to a floor above by means of this improved conveyer without the ashes abrading or destroying the belt.

In some instances the belt instead of being returned as shown in Fig. 1 may be returned as shown in Fig. 4, the idlers c and 0 being in front of the conveying portion of the belt instead of at the rear.

I claim as my invention- 1. The combination in an elevating-conveyer, of a single endless conveying-belt, guides therefor whereby the carrying-run of the belt is curved from a horizontal point to a point beyond the vertical,with means for driving the belt at such a speed that the material placed upon the belt at the base of the conveyer will be elevated thereby due to centrifugal action and adhesion and will be discharged from the upper end of the conveyer, substantially as described.

2. The combination in an elevating-0on veyer, of a single endless conveying-belt, guides therefor whereby the carrying-run of the belt is curved from a horizontal point to a point beyond the vertical, and means for abruptly changing the direction of the belt at the discharge-point, substantially as described.

3. The combination in a single elevatingconveyer, of a series of guiding sprocketwheels arranged in a curved line extending at the upper end beyond the vertical, chains at both sides adapted to the sprocketwheels,

a curved path vertically, with means for changing the curve of the belt at the upper end ofthe conveyer to discharge the material, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES M. DODGE.
